MARSHALL TVALLACE, OF LITTLE ROOK, ARKANSAS.

IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Patent No. 106,893, dated August30, 1870.

' To all whom 'it may concern:

Be it known that I, MARSHALL YVALLACE, of Little Rock, in the county ofPulaski and State of Arkansas, have invented a new and usefulImprovement in Presses; and l do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming part of this speeit` cation.

This invention rel-.ttes to improvements iu presses for hay and cottonand consists in the combination, with the ratchet-toothed stem of afollower, of pivoted levers, springpawls, hinged plates, levers, andsprings, as hereinafter shown and described.

Figure 1 is a sectional elevation of my improved press, and Fig. 2 is ahorizontal section of the same.

Similar letters of reference indicate correspondin g parts.

The case A is arranged on suitable supports B, so that the follower Owill work from the bottom upward. The stem l) of the follower isprovided with ratchet-teeth ou two opposite sides, and the levers E,provided with springactuated sliding pawls F, are employed for raisingit. Below the levers E are other spring-actuated sliding pawls, G, forholdin g it after being raised by the levers E.

To increase the leverage for pressing with great force I have appliedthe eccentric-levers H to the long arms ofthe levers E, as shown, forforcing them down, and I use the springs I under them for raising themup.

The eounterbalance-weights K are applied to the stem D by means of cordsworking over pulleys L, to assist in raising the follower; also toregulate the descent of the follower when the pawls are disconnectedfrom the stem D for the purpose. This is done by sliding the pawls backagainst their springs, and securin g them by the hinged plates O, whichare turned over against the studs P, provided on the said pawls for thepurpose. This arrangement makes a very simple and eicient press, whichmay be worked easily by one or two persons.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination ofthe standard D and pivoted leversE, provided with slidingpawls F,

studs P, and hinged plates o, and operated by levers H and springs I,all substantially as and for the purpose herein set forth.
